I have the Unity Desktop with Ubuntu 12.04 and "Add to panel" does not appear with Super+Alt+right click. I used "Add to panel" before with the classic Gnome desktop in previous versions of Ubuntu. Is this unavailable in the Unity Desktop or is there another way add apps to the top panel?

You might want to pose the two questions as two different ones. As for adding an app in the top panel, if you are using Gnome classic, you can simply drag the specific app from the drop down menu under "applications" onto the top panel.

To see the processes, you can choose "system monitor" from under application -> system tools.
